29 slice with very large step value.
30
Eric Smithee931b72010-01-27 00:28:29 +000031- Issue #7766: Change sys.getwindowsversion() return value to a named
32 tuple and add the additional members returned in an OSVERSIONINFOEX
33 structure. The new members are service_pack_major, service_pack_minor,
34 suite_mask, and product_type.
35
Antoine Pitroue80a6a42010-01-17 12:26:20 +000036- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
37 could crash in many places because of the PyByteArray_AS_STRING() macro
38 returning NULL. The macro now returns a statically allocated empty
39 string instead.
40
Antoine Pitrou64672132010-01-13 07:55:48 +000041- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

46 alpha 2, including: (1) a serious 'wrong output' bug that could
47 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
48 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000049 strings corresponding to subnormal values, (3) a memory leak for
50 some values large enough to cause overflow, and (4) a number of
51 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +000052

Antoine Pitroud840e512010-02-04 20:20:18 +000068- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
69 specified, rather than fall through to AF_PACKET (in the `socket` module).
70 Also, raise ValueError rather than TypeError when an unknown TIPC address
71 type is specified. Patch by Brian Curtin.
72
Vinay Sajip28c382f2010-02-04 18:48:53 +000073- logging: Implemented PEP 391.

83 :class:`zipfile.ZipExtFile` class used to represent files stored inside
84 an archive. The new implementation is significantly faster and can
85 be wrapped in a :class:`io.BufferedReader` object for more speedups.
86 It also solves an issue where interleaved calls to `read()` and
87 `readline()` give wrong results. Patch by Nir Aides.
88

94 the release file is empty.
95
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000096- Issue #7748: Since unicode values are supported for some metadata options
97 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
98 encoded string for them. This ensure that the upload and register commands
99 send the right values to PyPI without any error.
100
R. David Murrayed44dfa2010-01-16 05:15:17 +0000101- Issue #1670765: Prevent email.generator.Generator from re-wrapping

165Core and Builtins
166-----------------
167
Benjamin Petersonecdae192010-01-04 00:43:01 +0000168- The __complex__ method is now looked up on the class of instances to make it
169 consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000171- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
172 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
173
Mark Dickinson1b34d252010-01-01 17:27:30 +0000174- Issue #5080: A number of functions and methods previously produced a
175 DeprecationWarning when passed a float argument where an integer was
176 expected. These functions and methods now raise TypeError instead.
177 The majority of the effects of this change are in the extension
178 modules, but some core functions and methods are affected: notably
179 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
180 methods.
181
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000182- Issue #7604: Deleting an unset slotted attribute did not raise an

190
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000191- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
192 used to drop the time part of the result.
193
Mark Dickinson46572832009-12-27 14:55:57 +0000194- Issue #1811: improve accuracy and cross-platform consistency for
195 true division of integers: the result of a/b is now correctly
196 rounded for ints a and b (at least on IEEE 754 platforms), and in
197 particular does not depend on the internal representation of a long.
198
Ezio Melottif84caf42009-12-24 22:25:17 +0000199- Issue #6108: unicode(exception) and str(exception) should return the same
200 message when only __str__ (and not __unicode__) is overridden in the subclass.
201
Ronald Oussoren92919a62009-12-24 13:30:58 +0000202- Issue #6834: replace the implementation for the 'python' and 'pythonw'
203 executables on OSX.
204
205 These executables now work properly with the arch(1) command:
206 ``arch -ppc python`` will start a universal binary version of python
207 in PPC mode (unlike previous releases).
208
R. David Murray0a0a1a82009-12-14 16:28:26 +0000209- Issue #1680159: unicode coercion during an 'in' operation no longer masks
210 the underlying error when the coercion fails for the left hand operand.
211
Benjamin Peterson4895af42009-12-13 16:36:53 +0000212- Issue #7491: Metaclass's __cmp__ method was ignored.
213
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000214- Issue #7466: segmentation fault when the garbage collector is called

228 by Arfrever.
229
Antoine Pitrou80157252010-01-08 19:20:17 +0000230- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
231 renaming of `cPickle` to `pickle`. The warning was annoying since there's
232 no alternative to cPickle if you care about performance. Patch by Florent
233 Xicluna.
234

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000344- Issue #7419: setlocale() could crash the interpreter on Windows when called
345 with invalid values.
346
Eric Smithc4ab8332009-11-29 17:40:57 +0000347- Issue #3382: 'F' formatting for float and complex now convert the
348 result to upper case. This only affects 'inf' and 'nan', since 'f'
349 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000350
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000351- Remove switch from "%f" formatting to "%g" formatting for floats
352 larger than 1e50 in absolute value.
353
Mark Dickinson18cfada2009-11-23 18:46:41 +0000354- Remove restrictions on precision when formatting floats. E.g.,
355 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
356 requested 120 significant digits instead.
357
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000358- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000362- Issue #7085: Fix crash when importing some extensions in a thread
363 on MacOSX 10.6.
364
Mark Dickinsonb678de82009-11-19 18:41:49 +0000365- Issue #7117: repr(x) for a float x returns a result based on the
366 shortest decimal string that's guaranteed to round back to x under
367 correct rounding (with round-half-to-even rounding mode).
368 Previously it gave a string based on rounding x to 17 decimal digits.
369 repr(x) for a complex number behaves similarly. On platforms where
370 the correctly-rounded strtod and dtoa code is not supported (see below),
371 repr is unchanged.
372
373- Issue #7117: On almost all platforms: float-to-string and
374 string-to-float conversions within Python are now correctly rounded.
375 Places these conversions occur include: str for floats and complex
376 numbers; the float and complex constructors; old-style and new-style
377 numeric formatting; serialization and deserialization of floats and
378 complex numbers using marshal, pickle and json; parsing of float and
379 imaginary literals in Python code; Decimal-to-float conversion.
380
381 The conversions use a Python-adapted version of David Gay's
382 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
383 functions. This code is supported on Windows, and on Unix-like
384 platforms using gcc, icc or suncc as the C compiler. There may be a
385 small number of platforms on which correct operation of this code
386 cannot be guaranteed, so the code is not used: notably, this applies
387 to platforms where the C double format is not IEEE 754 binary64, and
388 to platforms on x86 hardware where the x87 FPU is set to 64-bit
389 precision and Python's configure script is unable to determine how
390 to change the FPU precision. On these platforms conversions use the
391 platform strtod and dtoa, as before.
392
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000393- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000394 now uses the correctly-rounded string <-> float conversions
395 described above (when available), and so produces correctly rounded
396 results that will display nicely under the float repr. There are
397 two related small changes: (1) round now accepts any class with an
398 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000399 floats for the second argument), and (2) an excessively large second
400 integer argument (e.g., round(1.234, 10**100)) no longer raises an
401 exception.
402
Philip Jenveyfab8be22009-11-17 02:42:26 +0000403- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

546 was locale aware; and (3) the interpretation of fromhex('-nan')
547 didn't match that of float('-nan').
548
Eric Smitha985a3a2009-05-05 18:26:08 +0000549- Issue #5920: For float.__format__, change the behavior with the
550 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
551 to be like 'g' but with at least one decimal point and with a
552 default precision of 12. Previously, the behavior the same but with
553 a default precision of 6. This more closely matches str(), and
554 reduces surprises when adding alignment flags to the empty
555 presentation type. This also affects the new complex.__format__ in
556 the same way.

Ronald Oussorene0154ed2009-03-30 23:10:35 +0000617- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
618 the end sys.path, for compatibility with the system install of Python.
619
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000620- Issue #4688: Add a heuristic so that tuples and dicts containing only
621 untrackable objects are not tracked by the garbage collector. This can
622 reduce the size of collections and therefore the garbage collection overhead
623 on long-running programs, depending on their particular use of datatypes.

627 are now between 50% and 150% faster.
628
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000629- Issue #4258: Make it possible to use base 2**30 instead of base
630 2**15 for the internal representation of integers, for performance
631 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
632 --enable-big-digits option to configure, which overrides the
633 default. Add sys.long_info structseq to provide information about
634 the internal format.
635
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000636- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

638
Mark Dickinson6b265f12009-03-18 16:07:26 +0000639- Issue #4474: PyUnicode_FromWideChar now converts characters outside
640 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
641 and sizeof(Py_UNICODE) == 2.
642
Eric Smith6f42edb2009-03-14 11:57:26 +0000643- Issue #5237: Allow auto-numbered fields in str.format(). For

645
Brett Cannon6c4cff02009-03-11 04:51:06 +0000646- Issue #3652: Make the 'line' argument for warnings.showwarning() a

648
Eric Smithe9fb6862009-02-20 14:02:36 +0000649- Issue #5247: Improve error message when unknown format codes are

651 float arguments.
652
Raymond Hettinger08259e82009-02-18 23:10:19 +0000653- Running Python with the -3 option now also warns about classic division
654 for ints and longs.
655
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000656- Issue #5260: Long integers now consume less memory: average
657 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
658 on a 64-bit system.
659
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000660- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

665
Benjamin Petersone18ef192009-01-20 14:21:16 +0000666- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
667
Georg Brandl29c6a282009-04-05 20:23:13 +0000668- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000669 were suppressing all exceptions. These include list(), filter(), map(),
670 zip(), and bytearray().
671
Benjamin Peterson596d3062009-01-19 15:42:23 +0000672- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

674
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000675- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

682 the interpreter segfault instead of raising an error.
683
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000684- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000691- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
692 collecting the oldest generation) so that allocating lots of objects without
693 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000694 Martin von Löwis at

698
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000699- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
700 an existing .py counterpart, override the co_filename attributes of all
701 code objects if the original filename is obsolete (which can happen if the
702 file has been renamed, moved, or if it is accessed through different paths).
703 Patch by Ziga Seilnacht and Jean-Paul Calderone.
704
Martin v. Löwis5344c992009-01-02 20:32:55 +0000705- Issue #4075: Use OutputDebugStringW in Py_FatalError.

712
Nick Coghlan180e4002008-12-30 01:18:48 +0000713- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
714 where the tp_hash and tp_dict slots are both NULL.
715
Benjamin Peterson7af65562008-12-29 17:56:58 +0000716- Issue #4764: With io.open, IOError.filename is set when trying to open a

724
Skip Montanarof205c132008-12-23 03:30:15 +0000725- Added test case to ensure attempts to read from a file opened for writing
726 fail.
727
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000728- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

739
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000740- Issue #4597: Fixed several opcodes that weren't always propagating
741 exceptions.
742
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000743- Issue #4445: Replace "sizeof(PyStringObject)" with
744 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
745 str instances. On a typical machine this saves 3 bytes of memory
746 (on average) per string allocation.
747
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000748- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
749 interpreter to abort ("Fatal Python error: Could not reset the stack!")
750 instead of throwing a MemoryError.
751
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000752- Issue #3689: The list reversed iterator now supports __length_hint__
753 instead of __len__. Behavior now matches other reversed iterators.
754
Benjamin Petersonc078f922008-11-21 22:27:24 +0000755- Issue #4367: Python would segfault during compiling when the unicodedata

757
Vinay Sajip213faca2008-12-03 23:22:58 +0000758- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000759 method on file objects with closefd=False. The file descriptor is still
760 kept open but the file object behaves like a closed file. The ``FileIO``
761 object also got a new readonly attribute ``closefd``.
762
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000763- Issue #4348: Some bytearray methods returned that didn't cause any change to
764 the bytearray, returned the same bytearray instead of a copy.
765
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000766- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
767

774
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000775- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
776 method does not return iterators for the 4th and 5th items.
777
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000778- Issue #4209: Enabling unicode_literals and the print_function in the same
779 __future__ import didn't work.
780
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000781- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000782 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000784- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
785 returned a path longer than MAX_PATH. (But It's doubtful this code path is
786 really executed because I cannot move to such directory on win2k)
787
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000788- Issue #4069: When set.remove(element) is used with a set element, the element
789 is temporarily replaced with an equivalent frozenset. But the eventual
790 KeyError would always report the empty frozenset([]) as the missing key. Now
791 it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000808- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
809 returned them on 64bit platforms.
810
Walter Dörwalded960ac2009-05-03 22:36:33 +0000811- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
812 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
813 step. This avoids problems with counting UTF-8 bytes that ignores the effect
814 of using the replace error handler in PyUnicode_DecodeUTF8().
815
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000816- Issue #3739: The unicode-internal encoder now reports the number of characters
817 consumed like any other encoder (instead of the number of bytes).
818
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000819- Issue #2422: When compiled with the ``--with-valgrind`` option, the
820 pymalloc allocator will be automatically disabled when running under
821 Valgrind. This gives improved memory leak detection when running
822 under Valgrind, while taking advantage of pymalloc at other times.

2001 - Packing a float now always gives a Deprecation Warning.
2002 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
2003
2004 - If x is not an int, long or float, then packing x will always
2005 result in struct.error. Previously an x with an __int__ method
2006 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
2007 ,'*i', '*l', and an x with a __long__ method could be packed by
2008 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
2009 TypeError used to be raised (with a confusing error message) for
2010 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

2206 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2207 ``printf`` function, whereas PyString_FromFormat has an independent

2305 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2306 for catch_warnings() also led to an improvement in the raising of a
2307 DeprecationWarning related to warnings.warn_explicit().

2331
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002332- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002373What's New in Python 2.6 beta 3?
2374================================
2375
Barry Warsaw07a4a382008-08-21 01:15:08 +00002376*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002377
2378Core and Builtins
2379-----------------
2380
Guido van Rossumf8402962008-08-20 15:01:50 +00002381- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2382 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2383 extensions do not automatically benefit from the class attribute
2384 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2385 to their tp_flags field if they care. This is a backwards
2386 compatibility feature; in 3.0, all types will use the cache by
2387 default.
2388
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002389- Keyword arguments can now follow starred arguments. (``f(a, *args,
2390 keyword=23)`` is now valid syntax.)
2391
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002392- ctypes function pointers that are COM methods have a boolean True
2393 value again.
2394
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002395- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2396 by denying s# to parse objects that have a releasebuffer procedure,
2397 and introducing s*.
2398
Georg Brandl1e13ea92008-08-11 09:07:59 +00002399- Issue #3537: Fix an assertion failure when an empty but presized dict
2400 object was stored in the freelist.
2401
Mark Dickinsonb6467572008-08-04 21:30:09 +00002402- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2403 ValueError consistently across platforms.
2404
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002405- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2406 (64bit Unix, for example), unichr() would truncate its argument and return
2407 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2408
Neal Norwitze7d8be82008-07-31 17:17:14 +00002409- Apply security patches from Apple.
2410
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002411- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2412 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2413
Antoine Pitrou92f82162008-07-25 22:22:08 +00002414- Issue #1819: function calls with several named parameters are now on
2415 average 35% faster (as measured by pybench).
2416
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002417- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2418 the python debugger steps into a class statement: the free variables (local
2419 variables defined in an outer scope) would be deleted from the outer scope.
2420
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002421- Issue #2620: Overflow checking when allocating or reallocating memory
2422 was not always being done properly in some python types and extension
2423 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2424 all been updated to perform better checks and places in the code that
2425 would previously leak memory on the error path when such an allocation
2426 failed have been fixed.
2427
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002428Library
2429-------
2430
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002431- Issue #3612: Added some missing basic types in ctypes.wintypes.
2432
Benjamin Petersone977ad42008-08-20 01:42:01 +00002433- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2434 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2435
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002436- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2437 version reported by these tools does not necessarily follow the python
2438 version numbering scheme, so the module is less strict when parsing it.
2439
Nick Coghlanf70385a2008-08-18 12:42:46 +00002440- Issue #2235: Added Py3k warnings for types which will become unhashable
2441 under the stricter __hash__ inheritance rules in 3.0. Several types
2442 which did not meet the rules for hash invariants and were already
2443 unhashable in 3.0 have now been explicitly flagged as unhashable in
2444 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2445 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2446
Brett Cannon88f801d2008-08-18 00:46:22 +00002447- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2455
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002456- Issue #3575: Incremental decoder's decode function now takes bytearray
2457 by using 's*' instead of 't#'.
2458
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002459- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002460 fails unicode conversion on 2nd parameter. (windows only)
2461
Facundo Batista94f243a2008-08-17 03:38:39 +00002462- Issue 2464. urllib2 now supports a malformation in the URL received
2463 in a redirect.
2464
Brett Cannonabe423e2008-08-16 21:47:07 +00002465- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002466 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002467
Facundo Batistaeb90b782008-08-16 14:44:07 +00002468- Issue #2776: fixed small issue when handling an URL with double slash
2469 after a 302 response in the case of not going through a proxy.
2470
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002471- Issue #2676: in the email package, content-type parsing was hanging on
2472 pathological input because of quadratic or exponential behaviour of a
2473 regular expression.
2474
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002475- Issue #3476: binary buffered reading through the new "io" library is now
2476 thread-safe.
2477
Brett Cannonbf3157b2008-08-14 05:00:03 +00002478- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2479 since mimetools itself is deprecated. Because modules are cached, all
2480 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2481
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002482- Issue #3134: shutil referenced undefined WindowsError symbol.
2483
Robert Schuppenies14646332008-08-10 11:01:53 +00002484- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2485 menu entries were not deleted.
2486
Brett Cannon83e81842008-08-09 23:30:55 +00002487- Copied the implementation of reduce() to _functools.reduce() to have a
2488 version that did not raise a DeprecationWarning under -3.
2489
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002490- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2491 a MemoryError rather than silently stop the iteration.
2492
Guido van Rossum59ce9012008-08-09 14:55:34 +00002493- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2494 to _sre.compile() will now be rejected. This should not affect anybody
2495 since the re.compile() function never generates invalid re-bytecode.
2496
Skip Montanaroa032bf42008-08-08 22:52:51 +00002497- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002516 asking for a specific length. This problem only affected files opened
2517 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002518

2544 mode 0600 rather than 000 under Unix.
2545
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002546- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002572Core and Builtins
2573-----------------
2574
Georg Brandl3e483f62008-07-16 22:57:41 +00002575- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2576 its methods now allow for items objects that can be converted to
2577 an integer using operator.index().
2578
Mark Dickinson64b7e502008-07-16 09:40:03 +00002579- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2580 produced a ValueError instead of giving the correct float.
2581
Eric Smitha5fa5a22008-07-16 00:11:49 +00002582- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2583 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2584
Mark Dickinson7103aa42008-07-15 19:08:33 +00002585- Issue #3008: the float type has a new instance method 'float.hex'
2586 and a new class method 'float.fromhex' to convert floating-point
2587 numbers to and from hexadecimal strings, respectively.
2588
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002589- Issue #2235: __hash__ is once again inherited by default. To allow
2590 collections.Hashable to remain meaningful in the presence of the
2591 default hash implementation (object.__hash__), it is now possible
2592 to explicit block inheritance of hash by setting __hash__=None at
2593 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2594 level.
2595
Nick Coghlanb028f502008-07-13 14:52:36 +00002596- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2597 the parent module cannot be found while performing an absolute import.
2598 This means that an incorrectly defined __package__ attribute will
2599 now only prevent relative imports in that module rather than causing
2600 all imports from that module to fail.
2601
Nick Coghlan14ff9942008-07-08 14:21:42 +00002602- Issue #2517: Allow unicode messages in Exceptions again by correctly
2603 bypassing the instance dictionary when looking up __unicode__ on
2604 new-style classes.
2605
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002606- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2607 set to a custom object whose write() method happens to install
2608 another file in sys.stdout.
2609
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002610- Issue #3088: Corrected a race condition in classes derived from
2611 threading.local: the first member set by a thread could be saved in
2612 another thread's dictionary.
2613
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002614- Issue #3004: Minor change to slice.indices(): the start and stop
2615 arguments are now treated identically, making the behaviour easier
2616 to describe and understand. For example, slice(None, -10,
2617 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2618 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2619 10, -1).
2620
Georg Brandl278fc502008-07-19 12:46:12 +00002621- Issue #3219: Calling a function with repeated keyword arguments,
2622 f(a=2, a=23), would not cause a syntax error. This was a regression
2623 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002624
Georg Brandl278fc502008-07-19 12:46:12 +00002625- Issue #2862: Make int and float freelist management consistent with
2626 other freelists. Changes their CompactFreeList apis into
2627 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002628
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002629Library
2630-------
2631
Thomas Heller57adf222008-08-14 19:10:48 +00002632- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2633 api functions without holding the GIL, which could lead to a fatal
2634 error when they failed.
2635
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002636- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2637

2643
Jesse Noller13e9d582008-07-16 14:32:36 +00002644- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2645 ForkingPickler.register() to resolve conflict with ctypes.
2646
Vinay Sajip51e65192008-07-18 09:01:10 +00002647- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002648
Thomas Heller880f5292008-07-15 19:39:38 +00002649- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2650 a valid dlerror() message.
2651
Thomas Heller2bad6572008-07-15 17:19:50 +00002652- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2653 incomplete structure was created.
2654
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002655- Issue #3339: dummy_thread.acquire() should not return None.
2656
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002657- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2658
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002659- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002660
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002661- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2662 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002663 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002664 content-length. The problem had been corrected in the 2.4 branch, but never
2665 merged into trunk.
2666
Georg Brandle78fbcc2008-07-05 10:13:36 +00002667- Issue #2663: add filtering capability to shutil.copytree().

2670
2671- Issue #1526: Allow more than 64k files to be added to Zip64 file.
2672
2673- Issue #1746: Correct handling of zipfile archive comments (previously
2674 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002675 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002676
Vinay Sajip51e65192008-07-18 09:01:10 +00002677- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002678 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002679
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002680- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2681 handling is now the same as that of other special attributes like __name__).
2682
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002683- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2684 removal in Python 3.0 in favor of urllib2.urlopen().

2696
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00002697- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Issue #1631171: Re-implement the 'warnings' module in C (the
3136 original Python code has been kept as backup). This will allow for
3137 using the 'warning's machinery in such places as the parser where
3138 use of pure Python code is not possible. Both the ``showarning()``
3139 and ``formatwarning()`` gain an optional 'line' argument which is
3140 not called by default for backwards-compatibility reasons. Setting
3141 ``warnings.showwarning()`` to an implementation that lacks support
3142 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003205- Issue #2550: The approach used by client/server code for obtaining
3206 ports to listen on in network-oriented tests has been refined in an
3207 effort to facilitate running multiple instances of the entire
3208 regression test suite in parallel without issue.
3209 test_support.bind_port() has been fixed such that it will always
3210 return a unique port -- which wasn't always the case with the
3211 previous implementation, especially if socket options had been set
3212 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3213 new implementation of bind_port() will actually raise an exception
3214 if it is passed an AF_INET/SOCK_STREAM socket with either the
3215 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3216 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3217 the socket it's been passed. This currently only applies to
3218 Windows. This option prevents any other sockets from binding to the
3219 host/port we've bound to, thus removing the possibility of the
3220 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3221 when a second SOCK_STREAM socket binds and accepts to a host/port
3222 that's already been bound by another socket. The optional preferred
3223 port parameter to bind_port() has been removed. Under no
3224 circumstances should tests be hard coding ports!
3225
3226 test_support.find_unused_port() has also been introduced, which will
3227 pass a temporary socket object to bind_port() in order to obtain an
3228 unused port. The temporary socket object is then closed and
3229 deleted, and the port is returned. This method should only be used
3230 for obtaining an unused port in order to pass to an external program
3231 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3232 a parameter to a server-oriented class that doesn't give you direct
3233 access to the underlying socket used.
3234
3235 Finally, test_support.HOST has been introduced, which should be used
3236 for the host argument of any relevant socket calls (i.e. bind and
3237 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003238
3239 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003241 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3242 test_asynchat and test_socket_ssl.
3243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244 It is now possible for multiple instances of the regression test
3245 suite to run in parallel without issue.

3512-----------------
3513
Fred Drakea8ee94b2008-03-01 02:45:07 +00003514- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003515 644. The mode is now inherited from the py file.

3518
3519- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003520
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003521- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003522 issue 215555 for a discussion.
3523
Eric Smitha73fbe72008-02-23 03:09:44 +00003524- Added the future_builtins module, which contains hex() and oct().
3525 These are the PEP 3127 version of these functions, designed to be
3526 compatible with the hex() and oct() builtins from Python 3.0. They
3527 differ slightly in their output formats from the existing, unchanged
3528 Python 2.6 builtins. The expected usage of the future_builtins
3529 module is:
3530 from future_builtins import hex, oct
3531
Eric Smith7ef40bf2008-02-20 23:34:22 +00003532- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3533 exponents for exponents with absolute value < 100. Follows C99
3534 standard. This is a change on Windows, which would use 3 digits.
3535 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3536 so that any alterations it does to the resulting string will be
3537 available in stringlib/formatter.h (for float.__format__).
3538
Eric Smith5a3c1352008-02-19 13:21:56 +00003539- Implemented PEP 3101, Advanced String Formatting. This adds a new
3540 builtin format(); a format() method for str and unicode; a
3541 __format__() method to object, str, unicode, int, long, float, and
3542 datetime; the class string.Formatter; and the C API
3543 PyObject_Format().
3544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Fixed several potential crashes, all caused by specially crafted
3546 __del__ methods exploiting objects in temporarily inconsistent
3547 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003548
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003549- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550 prevent a possible crash: an Abstract Base Class would try to access
3551 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003552
Georg Brandl3ee81df2008-05-17 18:14:43 +00003553- Fixed repr() and str() of complex numbers with infinity or nan as
3554 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003555
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556- Clear all free lists during a gc.collect() of the highest generation
3557 in order to allow pymalloc to free more arenas. Python may give back
3558 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003559
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560- Issue #2045: Fix an infinite recursion triggered when printing a
3561 subclass of collections.defaultdict, if its default_factory is set
3562 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003563
Christian Heimesf75dbef2008-02-08 00:11:31 +00003564- Fixed a minor memory leak in dictobject.c. The content of the free
3565 list was not freed on interpreter shutdown.
3566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Limit free list of method and builtin function objects to 256
3568 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003569
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3571 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003572 to compact the internal free lists of pre-allocted ints and floats.
3573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3575 calls. Python expected the return type int but the fork familie
3576 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003577
Georg Brandl3ee81df2008-05-17 18:14:43 +00003578- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3579 appear in the same code unit.

3585 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003586
Georg Brandl3ee81df2008-05-17 18:14:43 +00003587- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3588 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003589
Georg Brandl3ee81df2008-05-17 18:14:43 +00003590- Patch #1473257: generator objects gain a gi_code attribute. This is
3591 the same object as the func_code attribute of the function that
3592 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003593
Georg Brandl3ee81df2008-05-17 18:14:43 +00003594- Issue #1920: "while 0" statements were completely removed by the
3595 compiler, even in the presence of an "else" clause, which is
3596 supposed to be run when the condition is false. Now the compiler
3597 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003598
Guido van Rossumeead05f2008-01-24 18:21:02 +00003599- A few crashers fixed: weakref_in_del.py (issue #1377858);
3600 loosing_dict_ref.py (issue #1303614, test67.py);
3601 borrowed_ref_[34].py (not in tracker).
3602
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003603- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003604 suppressed while an extension is loaded by calling SetErrorMode in
3605 dynload_win.c. The error is still reported properly.
3606
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003608 several extension methods and modules do not work without unicode
3609 support.
3610
Georg Brandl26543b12008-01-21 18:36:51 +00003611- Issue #1882: when compiling code from a string, encoding cookies in the
3612 second line of code were not always recognized correctly.
3613
Georg Brandl14404b62008-01-19 19:27:05 +00003614- Issue #1679: "0x" was taken as a valid integer literal.
3615
Georg Brandl6caad7d2008-01-26 14:19:22 +00003616- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003617 added.
3618
Christian Heimesc94e2b52008-01-14 04:13:37 +00003619- sys.float_info / PyFloat_GetInfo: The floating point information
3620 object was converted from a dict to a specialized structseq object.
3621
Georg Brandl3ee81df2008-05-17 18:14:43 +00003622- Patch #1816: Added sys.flags structseq. It exposes the status of
3623 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003624
Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Objects/structseq.c: Implemented new structseq representation. The
3626 patch makes structseqs (e.g. the return value of os.stat) more
3627 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003628
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Patch #1700288: added a type attribute cache that caches method
3630 accesses, resulting in speedups in heavily object-oriented code.

3638 envvar and sys.dont_write_bytecode attribute. All these can be set
3639 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003640
Georg Brandl3ee81df2008-05-17 18:14:43 +00003641- Improve some exception messages when Windows fails to load an

3656 dictionary size. There is a new opcode, STORE_MAP, for adding
3657 entries to the dictionary.

3700
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- The enumerate() builtin function is no longer bounded to sequences
3702 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3703 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003704
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705- Issue #1686386: Tuple's tp_repr did not take into account the
3706 possibility of having a self-referential tuple, which is possible
3707 from C code. Nor did object's tp_str consider that a type's tp_str
3708 could do something that could lead to an inifinite recursion.
3709 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3710 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Issue #1164: It was possible to trigger deadlock when using the
3713 'print' statement to write to a file since the GIL was not released
3714 as needed. Now PyObject_Print() does the right thing along with
3715 various tp_print implementations of the built-in types and those in
3716 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003726 PyObject_Call() never calling back out to Python code to trigger
3727 recursion depth updates/checks. Required the creation of a static

Georg Brandl3ee81df2008-05-17 18:14:43 +00003746 __*__ attributes. (Some already existed, e.g., __doc__ and
3747 __name__.)

3754
Collin Winter62903052007-05-18 23:11:24 +00003755- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003756 "except E as target:". This is to provide forwards compatibility
3757 with Python 3.0.

3763
Vinay Sajip8549ce32007-05-06 17:53:37 +00003764- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003765 setting a plain string, ie don't expand to single letter identifiers.
3766
Raymond Hettinger13936692007-04-11 18:40:58 +00003767- Request #1191699: Slices can now be pickled.

3777
Guido van Rossum143b5642007-03-23 04:58:42 +00003778- Bug #1683368: The object.__init__() and object.__new__() methods are
3779 now stricter in rejecting excess arguments. The only time when
3780 either allows excess arguments is when it is not overridden and the
3781 other one is. For backwards compatibility, when both are
3782 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003783 warning later). Also, type.__init__() insists on the same signature
3784 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3787 object to complex using its __complex__() method before falling back
3788 to the __float__() method. Therefore, the functions in the cmath
3789 module now can operate on objects that define a __complex__()
3790 method.

3807
Georg Brandl7b9c5552007-03-12 14:30:05 +00003808- Bug #1678647: write a newline after printing an exception in any
3809 case, even when converting the value to a string failed.
3810
Georg Brandl871f1bc2007-03-12 13:17:36 +00003811- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812 its argument, if it exists. If not, it will work like before. This
3813 allows customizing the output of dir() in the presence of a
3814 __getattr__().

3824 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003825
Georg Brandlaa2321b2007-03-07 00:40:28 +00003826- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827 makes the filenames the warning module prints much more sensible
3828 when a PYTHONSTARTUP file is used.

3843
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004379 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00004397- Patch #1530482: add pydoc.render_doc() which returns the

4412
Georg Brandl92a6bae2007-03-13 17:43:32 +00004413- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004414 are set for invalid interpolation sequences that would lead to
4415 errors on reading back those values.

4469
Georg Brandl3ee81df2008-05-17 18:14:43 +00004470- unittest now verifies more of its assumptions. In particular,
4471 TestCase and TestSuite subclasses (not instances) are no longer
4472 accepted in TestSuite.addTest(). This should cause no
4473 incompatibility since it never made sense with ordinary subclasses
4474 -- the failure just occurred later, with a more cumbersome
4475 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004762 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004864 time so that opening a database previously created with the DB_DUP
4865 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4866 opens. Specifically: dictionary assignment to a DB object will
4867 replace all values for a given key when the database allows
4868 duplicate values. DB users should use DB.put(k, v) when they want
4869 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005148- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149 periodic threadstate and signal checking in tight loops. By
5150 default, this option is turned-off. It should only be enabled in
5151 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005208
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5210 to ``PyTuple_SetItem``, it can be used to populate a brand new

5223
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5225 of w# format code incorrectly truncated the length to an int, even
5226 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5227 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005257- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5258 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005259

Georg Brandl3ee81df2008-05-17 18:14:43 +00005285- Removed the macfs module. It had been deprecated since Python 2.5.
5286 This lead to the deprecation of macostools.touched() as it relied
